vaccine tool? What does that mean, if it was a vaccine I would just need to run the software once and I would be inoculated, this however do not seem to be the case? Is a behaviour monotoring tool, does it install a service or do I need to have the GUI running all the time – it is a little unclear if the load with Windows is only the GUI or the entire “protection package”.. Is any license terms available? Anyhow, thanks for a valiant efford.

It’s a vaccine, but it can (and probably will) be updated against new strains, hence the need to run at startup. It does not monitor behavior, it just uses some tricks to prevent those specific families of ransomware from infecting your system.
The software is provided AS-IS, without any implied or explicit guarantees. Redistribution is permitted.

He is referring to the fact that after a system has been infected with ransomware there isn't much hope. If the ransomware (cryptolocker or not) does its job properly, there should be no access to any files, including running AV processes.
